To suppress the noise which caused by the fuzzy character of XLPE sample, the size of the photodetector was determined based on the analysis of the light intensity distribution in the spatial frequency plane when the laser beam passing through the sample was collected by lens. A series of detectors were designed to eliminate the time response decreasing effect caused by the increasing of the detector size. The developed laser system could resolve defects of 40 um diameter in XLPE tape with the 120um diameter and 400Hz scanning laser beam. after above results was used.

Three-factor Jensen model reveals that 82% of all the funds have positive alphas and half of these alphas are statistically significant. And also, the average of the sample funds' alphas and the alpha of the equal-weighted fund are both positive and statistically significant. These illustrate that the sample funds have excellent performance when size and style factors are considered.(4) The study shows that Chinese funds as a whole do not exhibit excellent skills for stock selection and market timing.

X-ray analyses indicate that lattice parameters decrease due to Cu-doping; while XPS results show that Cu-doping leads to positive chemical shifts of the Cu 2P1/2 and La 3d5/2 and 3d3/2 levels, implying that Cu-O and La-O bondings are strengthened and their bond lengths are shortened; while magnetization measurements show that after 8 hours' Arannealing, the Neel temperature of Cu-rich sample is about 31K higher than that of the sample without Cu doping, indicating that the three-dimensional antiferromagnetic correlation is enhanced.

In order to reduce the conflict of L1P in CMT,we propose the policy of logic partition L1P Cache by n power of 2 and the competing loop lock.Now the fairness researchs always need single thread sample phase,we propose a novel fairness policy:FROCM,it doesn\'t need single thread sample phase.We propose ring cooperant L1 data Cache,which can reduce both the complexity of the design and the load of L2 Cache.We also propose a method to exchange threads dynamicly based on fast-shared data pool,it can detect the data consanguinity of two threads in real time and exchange them into one core rapidly.At last,we design and implement a dual-core and dual-thread VLIW prototype YHFT DSP/DS based on the above studies.In order to enhance the bandwidth of data path and reduce the delay of critical path delay of CMT processor,we design a 10R/6W register file full customly.
